RAILWAY CAR.

Original application nled November 21,- 1924, Serial '110. 751,260. Divided and this application led January 7, 1926.

My invention relates generally to improvements in railway tank cars, the present application being a division of my pending application for U. S. Letters Patent Serial No. 751,260, filed November 21,1924. My primary objects .are to provide in a car, and more particularly in a tank car having a box-like housing in which the tank is located, for the removal and replacement of the roof portion by a simple and quickly performed operation and without risk of damaging the car, in which structures it is sometimes necessary, to remove the tanks from the cars, as for example in the case of repairs to be made, in which case the tanks are lifted out of the housings; to provide a novel and simple construction of car of the character' stated; to provide for the proper thermal insulation of the car at the joint between the roofsection and the seotion thereof presenting the side and end walls; to provide for the so positioning of the refrigerating pipes in refrigerating cars of the type above referred to, that the tanks may be removed from, and replaced in, the, car housings through their upper ends, Without obstruction from the pipes and without requiring the disturbing of the position of the'latter, and other objects.' as will be manifest from the following description: Referring to the accompanying drawingszt Figure 1 is a plan view of a car of the type above referred to and embodying my improvements. Figure 2 is a plan sectional view of the car, the vsection being taken immediately below the roof portion thereof at the irregular line 2-*2 on Fig. 4 and viewed in the direction of the arrows, the tanks being shown in plan Figure 3 is an enlarged view in longitudinal sectional elevation of one end of the car, the section being takenat the line 3 on Fig. 2 and viewed in the direction of the arrow. Fig- .ure 4 is a section taken at the line 4 on Fig. 3, and viewed in the direction of the arrow.

fgure 5 is .an enlarged fragmentary seconal view taken at the line 5 on Fig. 1 and viewed in the direction of the arrow. Figure 6 is a broken section taken at the irregular line 6-6 on Fig. 5 and viewed in the direction of the arrows. Figure 7 is a plan view of the structure shown in Fig. 5, with the roof proper removed. Figure 8 Serial No. 79,822.

is a broken, enlarged, fragmentary sectional view taken at the line 8 on Fig.,1 and viewed in thedirection of the arrow; and Figure 9. a face view of one of the plurality of similar lifting lugs provided on the roof portion of the car.

The particular construction shown involves an underframe illustrated more especially in Figs. 3 and 4 and of the fishbelly, center-sill type, the center sill being represented at 10 and extending longitudivnally of the underframe from end to end thereof. This frame in addition to thel 10 and a body bolster 12 located toward opp0-..

site ends of the frame. The particular construction of center sill 10 shown which is of l hollow form, comprises side walls 13 spaced, apart and formed of plates 14 provided at their upper and lower edges with angle bars 15 and 16, respectively, rigidly secured thereto, and a plate 17 extending across the upper ends vof the side walls 14 and restingupon the angle bars 15 to -wbicb they are secured as for-example by rivets. The underframe shown is supported on wheel trucks, the wheels of" which are represented at 18, the form of underframe shown being of well known construction. The structure also comprises a platform, or floor portion, represented generally at 19 which is generally' of well known construction, this iioor por? tion being supported on the underfram and secured thereto in any desired manner, as for example in the manner well known in the art.

The. particular construction of car shown involves incorporation therein of two tanks proyided more especially for receiving fluids which it is desired be maintained at a given temperature regardless of atmospheric conditions, these tanks represented at 20 and i chorage means shown, and which form no part of the present invention, being that disclosed in my above-referred-to applicatipn for patent, it being suiiicient to say that each tank 2O extends at its lower portion` pling 25 from which a pipe 26 leads to a point adjacent an opening 27 in the side of the car and through which connection with this pipe may be made for filling the tanks.

Each tank 20 is provided at its lower portion at the end thereof adjacent the center of the car, with a valvecontrolled outlet 28, these outlets being connected together by a pipe 29 equipped with a coupling 30 for connection with a pipe for conveying the contents o the tanks to receptacles into which they are to be delivered, as for example to a storage tank (not shown).

The housing structure for the tanks 2O comprises .end and sidewalls 31 and 32, re-

spectively, and a roof portion 33, the wall portions 31 and 32 being built into each other and into the platform portion 19 of the car, as is common in refrigerating cars, these wall portions being of plural-wall construction with spaces therebetween containing any suitable thermal insulating material. The side walls 32 at the center portion of the car contains the usual large door openings 34 equipped with doors 35 and above these door openings, with the smaller openings 27 which would be equipped with removable closures (not shown).

The side and end walls 31 and 32 are provided along their upper edges with side and end plates 36 which together form a rectangular frame 37 built into the spaced wallforming portions of these walls. portion 33 of the housing is likewise formed of a-rectangular frame 38 of substantially the same size and shape as the frame 37 and comprising side plates 39 suitably connected together at their ends. the frame 38 resting upon the frame 37. The opposing surfaces of the frame 37 and 38 are internally grooved throughout their length at the sides and ends of the car, as represented at 40 and 41, respectively. these grooves containing thermal insulating materialrepresented at 42 provided for the purpose of insulating the interior of the housing at the joint between these housing sections. The frame 38 is provided at intervals along its inner surfaces, at its sides and ends, with cleats 43, those at the sides of the car'being located between adjacent carlines 44, as shown in Fig. 7 t-he cleats 43 which extend inwardly beyond the side plates 36- and 39 being' rigidly secured to the 'frame 38V by bolts 45` The roof l extending through sides plates 39 and the cleats 43. The frame structure thus presented has secured to it the roof proper represented at- 46 and the ceiling 47 spaced fromthe rooproper 46 to provide an air space with thermal insulation located therein, the ceiling 47 being secured in place as by nailing it to the carlines 44. The root` portion at its eleated portion is provided at intervals with vertically disposed bolts 48 having square upper ends 49 at which they extend into square openings 50 iu the cleats 43,' these bolts passing downwardly through the cleats 43, the ceiling 47, and through the horizontal flanges of the angle-clips 51, the nuts 52 of these bolts; bearing against the undersides of the clips-51. Plates 53 resting on the upper surfaces of the cleats 43 and secured thereto by bolts 54 and extending across the upper ends of the bolts 48, prevent upward displacement of the latter in the application of the roof portion 33 tothe side and end wall portions of the car. The angle clips 51 which are positioned at intervals in the angular spaces between the end and side walls 31 and 32 of the car and the roof portion 33 are connected with the side plates 36, the inner surfaces of which they overlap, by means of bolts 55 which extend through the side plates 36 and the depending flanges of the angle clips 51.

Provision is made for refrigerating the car, these means 'comprising refrigerating coils 56 for any suitable refrigerating medium, for example ammonia, arranged along the inner surfaces of the side walls 32. The coils 56 at each side of the car are connected 'together at their lower ends by pipes 57 extending belowthe platform 19 and provided with -filling and drawofl valves 58 and 105 at their upper ends-through couplings 59, by cross over pipes 60.

It will be understood from the foregoing that by removing the nuts 52 from the bolts 48, the roof portion of the car may be readily removed and replaced without dismantling any of the parts of the wall-forming portions of the car, to permit the tanks 20 to be bodily lifted,f as by cranes, out of the car housing and replaced therein as desired, it being understood that the piping located directly above `the tanks would Ibe first removed. To provide for the ready attachment of they lifting devicey to the roof portion 33 as for example, the lifting element 120 of a crane, the roof portion 33 is provided at 'intervals with upwardly extending apertired plates 61 securedthereto, as by bolts 6 As an additional means for rendering the joint between the frames 37 and 38, in tight condition, I prefer to provide for the 1ap. ping of the outermost members 63 and 64l of the frames 37 and 38 at their opposing? surfaces, as represented at 65,thereby form- 13 the inner surface of the housing.

ing. a lapped oint extending entirely around arranged that the ceiling portion 47 extends below the upper edge of the platesl 36, as shown in Fig. 5, formingv a lapped Joint at While I have illustrated and described a particular construction embodying my improvements, I do not wish to be understood as intending tolimit my invention thereto, as the salne may be variously modified and altered without departing from the spirit-of my invention.
